Hi Wesley,
Thanks for your suggestion. I will do the same while installing on the
latest machine.

I would also suggest upgrading to 14.7, it is a pretty straight forward
upgrade. Just install 14.7 and point your startsg script to the correct
installation directory.

Hi John,
Thanks for your suggestion. I need to change my machine
itself as it has only 8GB RAM and later on I realized that it is
DDR2 and not even DDR3 RAM.

Hi Glenn,
Thanks for your reply.
My machine has 8GB RAM and
maximum java heap size shown in MATLAB
was 2GB. Hence I tried to increase java
heap size to MAX 2GB and compiled
my old ROACH-1 design (mdl file later
updated using
'update_casper_blocks') which consists
of iADC and snap block and found
that it is taking 1:02hrs. But in
default condition of 128MB took 53:00
minutes.
This is bit surprising.
Since you're using more memory for the Matlab Java
heap, you might be
running out of physical memory and have begun paging
to virtual memory. 8
GB is marginal for these newer tools, unfortunatly.
Have you looked at
the system activity with vmstat while compiling?

Check your java heap size

too low. Search the mailing

Dear All,
I started
using ROACH-2 toolflow
recently. When I tried
to compile simple
ROACH-1 design of iADC board
with snap block
it took 45-minuts to
compile this design. Now
when I started to
compile ROACH-1
f-engine design on previous
day and it is still
in the stage of System
Generation today.
Can anyone tell why it
is taking so much long time
for
compilation and how to
reduce this compilation
time?
